In Tristram Geary’s Echo/Back, a strange virus strikes that enables the infected to time travel, but only in very short bursts—mere seconds into the past or future. The results are mostly chaotic, both for the world at large and the film’s protagonist, a thief who uses his strange ability to outmaneuver police in an extended fight scene.

There’s no dialogue here as the time-traveler weighs in with an exposition-heavy, voice-over monologue throughout the film. But despite Echo/Back’s quick seven-minute running time, you really get a sense of its high-concept premise—and how such a small, specific change to our concept of time would alter reality as we know it.
